Life cycle assessment and life cycle cost of university dormitories in the southeast China: Case study of the university town of Fuzhou

The results indicate that 1) the use stage, including operation and maintenance is the dominate part of the life cycle environmental impacts and cost of university dormitories. 2) The consumption of electricity constitutes the main elements causing the environmental impacts over the life cycle of university dormitories. The technology for more energy efficient building is more important than other factors. 3) The window, concrete, steel, and cement have the largest contribution to the embodied environmental impacts but with the relative small contribution to the life cycle cost. Therefore, two main improving opportunities for reducing the environmental impacts of Chinese university dormitories development are identified: 1) improving building with deep renovation for current dormitories and implementing low energy buildings standards for new built dormitories the buildings energy efficiency and 2) increasing the use of low environmental impacts building material by implementing the carbon tax on main building material and introducing timbers as structure material. Moreover, policies to promote the more renewable energy supply and the implementation of carbon capture and storage technology constitute another import issue.
